Import Upstream version 2.9.3
2022-11-14 17:01:35 +08:00
===================
astroid's ChangeLog
===================
What's New in astroid 2.10.0?
=============================
Release date: TBA
What's New in astroid 2.9.4?
============================
Release date: TBA
What's New in astroid 2.9.3?
============================
Release date: 2022-01-09
* Fixed regression where packages without a ``__init__.py`` file were
not recognized or imported correctly.
Closes #1327
What's New in astroid 2.9.2?
============================
Release date: 2022-01-04
* Fixed regression in ``astroid.scoped_nodes`` where ``_is_metaclass``
was not accessible anymore.
Closes #1325
What's New in astroid 2.9.1?
============================
Release date: 2021-12-31
* ``NodeNG.frame()`` and ``NodeNG.statement()`` will start raising ``ParentMissingError``
instead of ``AttributeError`` in astroid 3.0. This behaviour can already be triggered
by passing ``future=True`` to a ``frame()`` or ``statement()`` call.
* Prefer the module loader get_source() method in AstroidBuilder's
module_build() when possible to avoid assumptions about source
code being available on a filesystem. Otherwise the source cannot
be found and application behavior changes when running within an
embedded hermetic interpreter environment (pyoxidizer, etc.).
* Require Python 3.6.2 to use astroid.
* Removed custom ``distutils`` handling for resolving paths to submodules.
Ref #1321
* Fix ``deque.insert()`` signature in ``collections`` brain.
Closes #1260
* Fix ``Module`` nodes not having a ``col_offset``, ``end_lineno``, and ``end_col_offset``
attributes.
* Fix typing and update explanation for ``Arguments.args`` being ``None``.
* Fix crash if a variable named ``type`` is subscripted in a generator expression.
Closes PyCQA/pylint#5461
* Enable inference of dataclass import from marshmallow_dataclass.
This allows the dataclasses brain to recognize dataclasses annotated by marshmallow_dataclass.
* Resolve symlinks in the import path
Fixes inference error when the import path includes symlinks (e.g. Python
installed on macOS via Homebrew).
Closes #823
Closes PyCQA/pylint#3499
Closes PyCQA/pylint#4302
Closes PyCQA/pylint#4798
Closes PyCQA/pylint#5081
What's New in astroid 2.9.0?
============================
Release date: 2021-11-21
* Add ``end_lineno`` and ``end_col_offset`` attributes to astroid nodes.
* Always treat ``__class_getitem__`` as a classmethod.
* Add missing ``as_string`` visitor method for ``Unknown`` node.
Closes #1264
What's New in astroid 2.8.6?
============================
Release date: 2021-11-21
* Fix crash on inference of subclasses created from ``Class().__subclasses__``
Closes PyCQA/pylint#4982
* Fix bug with Python 3.7.0 / 3.7.1 and ``typing.NoReturn``.
Closes #1239
What's New in astroid 2.8.5?
============================
Release date: 2021-11-12
* Use more permissive versions for the ``typed-ast`` dependency (<2.0 instead of <1.5)
Closes #1237
* Fix crash on inference of ``__len__``.
Closes PyCQA/pylint#5244
* Added missing ``kind`` (for ``Const``) and ``conversion`` (for ``FormattedValue``) fields to repr.
* Fix crash with assignment expressions, nested if expressions and filtering of statements
Closes PyCQA/pylint#5178
* Fix incorrect filtering of assignment expressions statements
What's New in astroid 2.8.4?
============================
Release date: 2021-10-25
* Fix the ``scope()`` and ``frame()`` methods of ``NamedExpr`` nodes.
When these nodes occur in ``Arguments``, ``Keyword`` or ``Comprehension`` nodes these
methods now correctly point to the outer-scope of the ``FunctionDef``,
``ClassDef``, or ``Comprehension``.
* Fix the ``set_local`` function for ``NamedExpr`` nodes.
When these nodes occur in ``Arguments``, ``Keyword``, or ``Comprehension`` nodes these
nodes are now correctly added to the locals of the ``FunctionDef``,
``ClassDef``, or ``Comprehension``.
What's New in astroid 2.8.3?
============================
Release date: 2021-10-17
* Add support for wrapt 1.13

suited for pylint. Import them from ``pylint.checkers.utils`` instead
(requires pylint ``2.12``).
* Suppress the conditional between applied brains and dynamic import authorized
modules. (Revert the "The transforms related to a module are applied only if this
module has not been explicitly authorized to be imported" of version 2.7.3)
* Adds a brain to infer the ``numpy.ma.masked_where`` function.

What's New in astroid 2.6.0?
============================
Release date: 2021-06-22
* Appveyor and travis are no longer used in the continuous integration
* ``setuptools_scm`` has been removed and replaced by ``tbump`` in order to not
have hidden runtime dependencies to setuptools
* ``NodeNg``, the base node class, is now accessible from ``astroid`` or
``astroid.nodes`` as it can be used for typing.
* Update enum brain to improve inference of .name and .value dynamic class
attributes
Closes PyCQA/pylint#1932
Closes PyCQA/pylint#2062
Closes PyCQA/pylint#2306
* Removed ``Repr``, ``Exec``, and ``Print`` nodes as the ``ast`` nodes
they represented have been removed with the change to Python 3
* Deprecate ``Ellipsis`` node. It will be removed with the next minor release.
Checkers that already support Python 3.8+ work without issues. It's only
necessary to remove all references to the ``astroid.Ellipsis`` node.
This changes will make development of checkers easier as the resulting tree for Ellipsis
will no longer depend on the python version. **Background**: With Python 3.8 the
``ast.Ellipsis`` node, along with ``ast.Str``, ``ast.Bytes``, ``ast.Num``,
and ``ast.NamedConstant`` were merged into ``ast.Constant``.
* Deprecated ``Index`` and ``ExtSlice`` nodes. They will be removed with the
next minor release. Both are now part of the ``Subscript`` node.
Checkers that already support Python 3.9+ work without issues.
It's only necessary to remove all references to the ``astroid.Index`` and
``astroid.ExtSlice`` nodes. This change will make development of checkers
easier as the resulting tree for ``ast.Subscript`` nodes will no longer
depend on the python version. **Background**: With Python 3.9 ``ast.Index``
and ``ast.ExtSlice`` were merged into the ``ast.Subscript`` node.
* Updated all Match nodes to be internally consistent.
* Add ``Pattern`` base class.
What's New in astroid 2.5.8?
============================
Release date: 2021-06-07

* The ``shape`` attribute of a ``numpy ndarray`` is now a ``ndarray``
Close PyCQA/pylint#3139
* Don't ignore special methods when inspecting gi classes
Close #728
* Added transform for ``scipy.gaussian``
* Add support for inferring properties.
* Added a brain for ``responses``
* Allow inferring positional only arguments.
* Retry parsing a module that has invalid type comments
It is possible for a module to use comments that might be interpreted
as type comments by the `ast` library. We do not want to completely crash on those
invalid type comments.
Close #708
* Scope the inference to the current bound node when inferring instances of classes
When inferring instances of classes from arguments, such as ``self``
in a bound method, we could use as a hint the context's ``boundnode``,
which indicates the instance from which the inference originated.
As an example, a subclass that uses a parent's method which returns
``self``, will override the ``self`` to point to it instead of pointing
to the parent class.
Close PyCQA/pylint#3157
* Add support for inferring exception instances in all contexts
We were able to infer exception instances as ``ExceptionInstance``
only for a handful of cases, but not all. ``ExceptionInstance`` has
support for better inference of `.args` and other exception related
attributes that normal instances do not have.
This additional support should remove certain false positives related
to ``.args`` and other exception attributes in ``pylint``.
Close PyCQA/pylint#2333
* Add more supported parameters to ``subprocess.check_output``
Close #722
* Infer args unpacking of ``self``
Certain stdlib modules use ``*args`` to encapsulate
the ``self`` parameter, which results in uninferable
instances given we rely on the presence of the ``self``
argument to figure out the instance where we should be
setting attributes.
Close PyCQA/pylint#3216
* Clean up setup.py
Make pytest-runner a requirement only if running tests, similar to what was
done with McCabe.
Clean up the setup.py file, resolving a handful of minor warnings with it.

* Can access per argument type comments for positional only and keyword only arguments.
The comments are accessed through through the new
``Arguments.type_comment_posonlyargs`` and

What's New in astroid 2.3.2?
============================
Release date: 2019-10-18
* All type comments have as parent the corresponding `astroid` node
Until now they had as parent the builtin `ast` node which meant
we were operating with primitive objects instead of our own.
Close PyCQA/pylint#3174
* Pass an inference context to `metaclass()` when inferring an object type
This should prevent a bunch of recursion errors happening in pylint.
Also refactor the inference of `IfExp` nodes to use separate contexts
for each potential branch.

What's New in astroid 2.3.1?
============================
Release date: 2019-09-30
* A transform for the builtin `dataclasses` module was added.
This should address various `dataclasses` issues that were surfaced
even more after the release of pylint 2.4.0.
In the previous versions of `astroid`, annotated assign nodes were
allowed to be retrieved via `getattr()` but that no longer happens
with the latest `astroid` release, as those attribute are not actual
attributes, but rather virtual ones, thus an operation such as `getattr()`
does not make sense for them.
* Update attr brain to partly understand annotated attributes
Close #656
What's New in astroid 2.3.0?
============================
Release date: 2019-09-24
* Add a brain tip for ``subprocess.check_output``

* Remove NodeNG.nearest method because of lack of usage in astroid and pylint.

* Allow importing wheel files. Close #541
* Annotated AST follows PEP8 coding style when converted to string.
* Fix a bug where defining a class using type() could cause a DuplicateBasesError.
Close #644
* Dropped support for Python 3.4.
* Numpy brain support is improved.
Numpy's fundamental type ``numpy.ndarray`` has its own brain : ``brain_numpy_ndarray`` and
each numpy module that necessitates brain action has now its own numpy brain :
- ``numpy.core.numeric``
- ``numpy.core.function_base``
- ``numpy.core.multiarray``

* Drop a superfluous and wrong callcontext when inferring the result of a context manager
Close PyCQA/pylint#2859
* ``igetattr`` raises ``InferenceError`` on re-inference of the same object
This prevents ``StopIteration`` from leaking when we encounter the same
object in the current context, which could result in various ``RuntimeErrors``
leaking in other parts of the inference.
Until we get a global context per inference, the solution is sort of a hack,
as with the suggested global context improvement, we could theoretically
reuse the same inference object.

* Variable annotations can no longer be retrieved with `ClassDef.getattr`
Unless they have an attached value, class variable annotations can no longer
be retrieved with `ClassDef.getattr.`
* Improved builtin inference for ``tuple``, ``set``, ``frozenset``, ``list`` and ``dict``
We were properly inferring these callables *only* if they had consts as
values, but that is not the case most of the time. Instead we try to infer
the values that their arguments can be and use them instead of assuming
Const nodes all the time.

we weren't cloning all the subtree of the f-string expression for attaching the correct

* mro() can be computed for classes with old style classes in the hierarchy
What's New in astroid 1.5.0?
============================
Release date: 2017-04-13
* Arguments node gained a new attribute, ``kwonlyargs_annotations``
This new attribute holds the annotations for the keyword-only
arguments.
* `namedtuple` inference now understands `rename` keyword argument
* Classes can now know their definition-time arguments.
Classes can support keyword arguments, which are passed when
a class is constructed using ``__new__``.
* Add support for inferring typing.NamedTuple.
* ClassDef now supports __getitem__ inference through the metaclass.
* getitem() method accepts nodes now, instead of Python objects.
* Add support for explicit namespace packages, created with pkg_resources.
* Add brain tips for _io.TextIOWrapper's buffer and raw attributes.
* Add `returns` into the proper order in FunctionDef._astroid_fields
The order is important, since it determines the last child,
which in turn determines the last line number of a scoped node.
* Add brain tips for functools.lru_cache.
* New function, astroid.extract_node, exported out from astroid.test_utils.
* Stop saving assignment locals in ExceptHandlers, when the context is a store.
This fixes a tripping case, where the RHS of a ExceptHandler can be redefined
by the LHS, leading to a local save. For instance, ``except KeyError, exceptions.IndexError``
could result in a local save for IndexError as KeyError, resulting in potential unexpected
inferences. Since we don't lose a lot, this syntax gets prohibited.
* Fix a crash which occurred when the class of a namedtuple could not be inferred.
* Add support for implicit namespace packages (PEP 420)
This change involves a couple of modifications. First, we're relying on a
spec finder protocol, inspired by importlib's ModuleSpec, for finding where
a file or package is, using importlib's PathFinder as well, which enable
us to discover namespace packages as well.
This discovery is the center piece of the namespace package support,
the other part being the construction of a dummy Module node whenever
a namespace package root directory is requested during astroid's import
references.
* Introduce a special attributes model
Through this model, astroid starts knowing special attributes of certain Python objects,
such as functions, classes, super objects and so on. This was previously possible before,
but now the lookup and the attributes themselves are separated into a new module,
objectmodel.py, which describes, in a more comprehensive way, the data model of each
object.
* Exceptions have their own object model
Some of exceptions's attributes, such as .args and .message,
can't be inferred correctly since they are descriptors that get
transformed into the proper objects at runtime. This can cause issues
with the static analysis, since they are inferred as different than
what's expected. Now when we're creating instances of exceptions,
we're inferring a special object that knows how to transform those
runtime attributes into the proper objects via a custom object model.
Closes issue #81
* dict.values, dict.keys and dict.items are properly
inferred to their corresponding type, which also
includes the proper containers for Python 3.
* Fix a crash which occurred when a method had a same name as a builtin object,
decorated at the same time by that builtin object ( a property for instance)
* The inference can handle the case where the attribute is accessed through a subclass
of a base class and the attribute is defined at the base class's level,
by taking in consideration a redefinition in the subclass.
This should fix https://github.com/PyCQA/pylint/issues/432
* Calling lambda methods (defined at class level) can be understood.
* Don't take in consideration invalid assignments, especially when __slots__
declaration forbids them.
Close issue #332
* Functional form of enums support accessing values through __call__.
* Brain tips for the ssl library.
* decoratornames() does not leak InferenceError anymore.
* wildcard_imported_names() got replaced by _public_names()
Our understanding of wildcard imports through __all__ was
half baked to say at least, since we couldn't account for
modifications of the list, which results in tons of false positives.
Instead, we replaced it with _public_names(), a method which returns
all the names that are publicly available in a module, that is that
don't start with an underscore, even though this means that there
is a possibility for other names to be leaked out even though
they are not present in the __all__ variable.
The method is private in 1.4.X.
* unpack_infer raises InferenceError if it can't operate
with the given sequences of nodes.
* Support accessing properties with super().
* Enforce strong updates per frames.
When looking up a name in a scope, Scope.lookup will return
only the values which will be reachable after execution, as seen
in the following code:
a = 1
a = 2
In this case it doesn't make sense to return two values, but
only the last one.
* Add support for inference on threading.Lock
As a matter of fact, astroid can infer on threading.RLock,
threading.Semaphore, but can't do it on threading.Lock (because it comes
from an extension module).
* pkg_resources brain tips are a bit more specific,
by specifying proper returns.
* The slots() method conflates all the slots from the ancestors
into a list of current and parent slots.
We're doing this because this is the right semantics of slots,
they get inherited, as long as each parent defines a __slots__
entry.
* Some nodes got a new attribute, 'ctx', which tells in which context
the said node was used.
The possible values for the contexts are `Load` ('a'), `Del`
('del a'), `Store` ('a = 4') and the nodes that got the new
attribute are Starred, Subscript, List and Tuple. Closes issue #267.
* relative_to_absolute_name or methods calling it will now raise
TooManyLevelsError when a relative import was trying to
access something beyond the top-level package.
* AstroidBuildingException is now AstroidBuildingError. The first
name will exist until astroid 2.0.
* Add two new exceptions, AstroidImportError and AstroidSyntaxError.
They are subclasses of AstroidBuildingException and are raised when
a module can't be imported from various reasons.
Also do_import_module lets the errors to bubble up without converting
them to InferenceError. This particular conversion happens only
during the inference.
* Revert to using printf-style formatting in as_string, in order
to avoid a potential problem with encodings when using .format.
Closes issue #273. Patch by notsqrt.
* assigned_stmts methods have the same signature from now on.
They used to have different signatures and each one made
assumptions about what could be passed to other implementations,
leading to various possible crashes when one or more arguments
weren't given. Closes issue #277.
* Fix metaclass detection, when multiple keyword arguments
are used in class definition.
* Add support for annotated variable assignments (PEP 526)
* Starred expressions are now inferred correctly for tuple,
list, set, and dictionary literals.
* Support for asynchronous comprehensions introduced in Python 3.6.
Fixes #399. See PEP530 for details.
What's New in astroid 1.4.1?
============================
Release date: 2015-11-29
* Add support for handling Uninferable nodes when calling as_string
Some object, for instance List or Tuple can have, after inference,
Uninferable as their elements, happening when their components
weren't couldn't be inferred properly. This means that as_string
needs to cope with expecting Uninferable nodes part of the other
nodes coming for a string transformation. The patch adds a visit
method in AsString and ``accept`` on Yes / Uninferable nodes.
Closes issue #270.
What's New in astroid 1.4.0?
============================
Release date: 2015-11-29
* Class.getattr('__mro__') returns the actual MRO. Closes issue #128.
* The logilab-common dependency is not needed anymore as the needed code
was integrated into astroid.
* Generated enum member stubs now support IntEnum and multiple
base classes.
* astroid.builder.AstroidBuilder.string_build and
astroid.builder.AstroidBuilder.file_build are now raising
AstroidBuildingException when the parsing of the string raises
a SyntaxError.
* Add brain tips for multiprocessing.Manager and
multiprocessing.managers.SyncManager.
* Add some fixes which enhances the Jython support.
The fix mostly includes updates to modutils, which is
modified in order to properly lookup paths from live objects,
which ends in $py.class, not pyc as for Python 2,
Closes issue #83.
* The Generator objects inferred with `infer_call_result`
from functions have as parent the function from which they
are returned.
* Add brain tips for multiprocessing post Python 3.4+,
where the module level functions are retrieved with getattr
from a context object, leading to many no-member errors
in Pylint.
* Understand partially the 3-argument form of `type`.
The only change is that astroid understands members
passed in as dictionaries as the third argument.
* .slots() will return an empty list for classes with empty slots.
Previously it returned None, which is the same value for
classes without slots at all. This was changed in order
to better reflect what's actually happening.
* Improve the inference of Getattr nodes when dealing with
abstract properties from the abc module.
In astroid.bases.Instance._wrap_attr we had a detection
code for properties, which basically inferred whatever
a property returned, passing the results up the stack,
to the igetattr() method. It handled only the builtin property
but the new patch also handles a couple of other properties,
such as abc.abstractproperty.
* UnboundMethod.getattr calls the getattr of its _proxied object
and doesn't call super(...) anymore.
It previously crashed, since the first ancestor in its mro was
bases.Proxy and bases.Proxy doesn't implement the .getattr method.
Closes issue #91.
* Don't hard fail when calling .mro() on a class which has
combined both newstyle and old style classes. The class
in question is actually newstyle (and the __mro__ can be
retrieved using Python).
.mro() fallbacks to using .ancestors() in that case.
* Class.local_attr and Class.local_attr_ancestors uses internally
a mro lookup, using .mro() method, if they can.
That means for newstyle classes, when trying to lookup a member
using one of these functions, the first one according to the
mro will be returned. This reflects nicely the reality,
but it can have as a drawback the fact that it is a behaviour
change (the previous behaviour was incorrect though). Also,
having bases which can return multiple values when inferred
will not work with the new approach, because .mro() only
retrieves the first value inferred from a base.
* Expose an implicit_metaclass() method in Class. This will return
a builtins.type instance for newstyle classes.
* Add two new exceptions for handling MRO error cases. DuplicateBasesError
is emitted when duplicate bases are found in a class,
InconsistentMroError is raised when the method resolution is determined
to be inconsistent. They share a common class, MroError, which
is a subclass of ResolveError, meaning that this change is backwards
compatible.
* Classes aren't marked as interfaces anymore, in the `type` attribute.
* Class.has_dynamic_getattr doesn't return True for special methods
which aren't implemented in pure Python, as it is the case for extension modules.
Since most likely the methods were coming from a live object, this implies
that all of them will have __getattr__ and __getattribute__ present and it
is wrong to consider that those methods were actually implemented.
* Add basic support for understanding context managers.
Currently, there's no way to understand whatever __enter__ returns in a
context manager and what it is binded using the ``as`` keyword. With these changes,
we can understand ``bar`` in ``with foo() as bar``, which will be the result of __enter__.
* Add a new type of node, called *inference objects*. Inference objects are similar with
AST nodes, but they can be obtained only after inference, so they can't be found
inside the original AST tree. Their purpose is to handle at astroid level
some operations which can't be handled when using brain transforms.
For instance, the first object added is FrozenSet, which can be manipulated
at astroid's level (inferred, itered etc). Code such as this 'frozenset((1,2))'
will not return an Instance of frozenset, without having access to its
content, but a new objects.FrozenSet, which can be used just as a nodes.Set.
* Add a new *inference object* called Super, which also adds support for understanding
super calls. astroid understands the zero-argument form of super, specific to
Python 3, where the interpreter fills itself the arguments of the call. Also, we
are understanding the 2-argument form of super, both for bounded lookups
(super(X, instance)) as well as for unbounded lookups (super(X, Y)),
having as well support for validating that the object-or-type is a subtype
of the first argument. The unbounded form of super (one argument) is not
understood, since it's useless in practice and should be removed from
Python's specification. Closes issue #89.
* Add inference support for getattr builtin. Now getattr builtins are
properly understood. Closes issue #103.
* Add inference support for hasattr builtin. Closes issue #102.
* Add 'assert_equals' method in nose.tools's brain plugin.
* Don't leak StopIteration when inferring invalid UnaryOps (+[], +None etc.).
* Improve the inference of UnaryOperands.
When inferring unary operands, astroid looks up the return value
of __pos__, __neg__ and __invert__ to determine the inferred value
of ``~node``, ``+node`` or ``-node``.
* Improve the inference of six.moves, especially when using `from ... import ...`
syntax. Also, we added a new fail import hook for six.moves, which fixes the
import-error false positive from pylint. Closes issue #107.
* Make the first steps towards detecting type errors for unary and binary
operations.
In exceptions, one object was added for holding information about a possible
UnaryOp TypeError, object called `UnaryOperationError`. Even though the name
suggests it's an exception, it's actually not one. When inferring UnaryOps,
we use this special object to mark a possible TypeError,
object which can be interpreted by pylint in order to emit a new warning.
We are also exposing a new method for UnaryOps, called `type_errors`,
which returns a list of UnaryOperationsError.
* A new method was added to the AST nodes, 'bool_value'. It is used to deduce
the value of a node when used in a boolean context, which is useful
for both inference, as well as for data flow analysis, where we are interested
in what branches will be followed when the program will be executed.
`bool_value` returns True, False or YES, if the node's boolean value can't
be deduced. The method is used when inferring the unary operand `not`.
Thus, `not something` will result in calling `something.bool_value` and
negating the result, if it is a boolean.
* Add inference support for boolean operations (`and` and `not`).
* Add inference support for the builtin `callable`.
* astroid.inspector was moved to pylint.pyreverse, since
it is the only known client of this module. No other change
was made to the exported API.
* astroid.utils.ASTWalker and astroid.utils.LocalsVisitor
were moved to pylint.pyreverse.utils.
* Add inference support for the builtin `bool`.
* Add `igetattr` method to scoped_nodes.Function.
* Add support for Python 3.5's MatMul operation: see PEP 465 for more
details.
* NotImplemented is detected properly now as being part of the
builtins module. Previously trying to infer the Name(NotImplemented)
returned an YES object.
* Add astroid.helpers, a module of various useful utilities which don't
belong yet into other components. Added *object_type*, a function
which can be used to obtain the type of almost any astroid object,
similar to how the builtin *type* works.
* Understand the one-argument form of the builtin *type*.
This uses the recently added *astroid.helpers.object_type* in order to
retrieve the Python type of the first argument of the call.
* Add helpers.is_supertype and helpers.is_subtype, two functions for
checking if an object is a super/sub type of another.
* Improve the inference of binary arithmetic operations (normal
and augmented).
* Add support for retrieving TypeErrors for binary arithmetic operations.
The change is similar to what was added for UnaryOps: a new method
called *type_errors* for both AugAssign and BinOp, which can be used
to retrieve type errors occurred during inference. Also, a new
exception object was added, BinaryOperationError.
* Lambdas found at class level, which have a `self` argument, are considered
BoundMethods when accessing them from instances of their class.
* Add support for multiplication of tuples and lists with instances
which provides an __index__ returning-int method.
* Add support for indexing containers with instances which provides
an __index__ returning-int method.
* Star unpacking in assignments returns properly a list,
not the individual components. Closes issue #138.
* Add annotation support for function.as_string(). Closes issue #37.
* Add support for indexing bytes on Python 3.
* Add support for inferring subscript on instances, which will
use __getitem__. Closes issue #124.
* Add support for pkg_resources.declare_namespaces.
* Move pyreverse specific modules and functionality back into pyreverse
(astroid.manager.Project, astroid.manager.Manager.project_from_files).
* Understand metaclasses added with six.add_metaclass decorator. Closes issue #129.
* Add a new convenience API, `astroid.parse`, which can be used to retrieve
an astroid AST from a source code string, similar to how ast.parse can be
used to obtain a Python AST from a source string. This is the test_utils.build_module
promoted to a public API.
* do_import_module passes the proper relative_only flag if the level is higher
than 1. This has the side effect that using `from .something import something`
in a non-package will finally result in an import-error on Pylint's side.
Until now relative_only was ignored, leading to the import of `something`,
if it was globally available.
* Add get_wrapping_class API to scoped_nodes, which can be used to
retrieve the class that wraps a node.
* Class.getattr looks by default in the implicit and the explicit metaclasses,
which is `type` on Python 3.
Closes issue #114.
* There's a new separate step for transforms.
Until now, the transforms were applied at the same time the tree was
being built. This was problematic if the transform functions were
using inference, since the inference was executed on a partially
constructed tree, which led to failures when post-building
information was needed (such as setting the _from_names
for the From imports).
Now there's a separate step for transforms, which are applied
using transform.TransformVisitor.
There's a couple of other related changes:
* astroid.parse and AstroidBuilder gained a new parameter
`apply_transforms`, which is a boolean flag, which will
control if the transforms are applied. We do this because
there are uses when the vanilla tree is wanted, without
any implicit modification.
* the transforms are also applied for builtin modules,
as a side effect of the fact that transform visiting
was moved in AstroidBuilder._post_build from
AstroidBuilder._data_build.
Closes issue #116.
* Class._explicit_metaclass is now a public API, in the form of
Class.declared_metaclass.
Class.mro remains the de facto method for retrieving the metaclass
of a class, which will also do an evaluation of what declared_metaclass
returns.
* Understand slices of tuples, lists, strings and instances with support
for slices.
Closes issue #137.
* Add proper grammatical names for `inferred` and `ass_type` methods,
namely `inferred` and `assign_type`.
The old methods will raise PendingDeprecationWarning, being slated
for removal in astroid 2.0.
* Add new AST names in order to be similar to the ones
from the builtin ast module.
With this change, Getattr becomes Attributes, Backquote becomes
Repr, Class is ClassDef, Function is FunctionDef, Discard is Expr,
CallFunc is Call, From is ImportFrom, AssName is AssignName
and AssAttr is AssignAttr. The old names are maintained for backwards
compatibility and they are interchangeable, in the sense that using
Discard will use Expr under the hood and the implemented visit_discard
in checkers will be called with Expr nodes instead. The AST does not
contain the old nodes, only the interoperability between them hides this
fact. Recommendations to move to the new nodes are emitted accordingly,
the old names will be removed in astroid 2.0.
* Add support for understanding class creation using `type.__new__(mcs, name, bases, attrs)``
Until now, inferring this kind of calls resulted in Instances, not in classes,
since astroid didn't understand that the presence of the metaclass in the call
leads to a class creating, not to an instance creation.
* Understand the `slice` builtin. Closes issue #184.
* Add brain tips for numpy.core, which should fix Pylint's #453.
* Add a new node, DictUnpack, which is used to represent the unpacking
of a dictionary into another dictionary, using PEP 448 specific syntax
``({1:2, **{2:3})``
This is a different approach than what the builtin ast module does,
since it just uses None to represent this kind of operation,
which seems conceptually wrong, due to the fact the AST contains
non-AST nodes. Closes issue #206.
What's New in astroid 1.3.6?
============================
Release date: 2015-03-14
* Class.slots raises NotImplementedError for old style classes.
Closes issue #67.
* Add a new option to AstroidManager, `optimize_ast`, which
controls if peephole optimizer should be enabled or not.
This prevents a regression, where the visit_binop method
wasn't called anymore with astroid 1.3.5, due to the differences
in the resulting AST. Closes issue #82.
What's New in astroid 1.3.5?
============================
Release date: 2015-03-11
* Add the ability to optimize small ast subtrees,
with the first use in the optimization of multiple
BinOp nodes. This removes recursivity in the rebuilder
when dealing with a lot of small strings joined by the
addition operator. Closes issue #59.
* Obtain the methods for the nose brain tip through an
unittest.TestCase instance. Closes Pylint issue #457.
* Fix a crash which occurred when a class was the ancestor
of itself. Closes issue #78.
* Improve the scope_lookup method for Classes regarding qualified
objects, with an attribute name exactly as one provided in the
class itself.
For example, a class containing an attribute 'first',
which was also an import and which had, as a base, a qualified name
or a Gettattr node, in the form 'module.first', then Pylint would
have inferred the `first` name as the function from the Class,
not the import. Closes Pylint issue #466.
* Implement the assigned_stmts operation for Starred nodes,
which was omitted when support for Python 3 was added in astroid.
Closes issue #36.
What's New in astroid 1.3.4?
============================
Release date: 2015-01-17
* Get the first element from the method list when obtaining
the functions from nose.tools.trivial. Closes Pylint issue #448.
What's New in astroid 1.3.3?
============================
Release date: 2015-01-16
* Restore file_stream to a property, but deprecate it in favour of
the newly added method Module.stream. By using a method instead of a
property, it will be easier to properly close the file right
after it is used, which will ensure that no file descriptors are
leaked. Until now, due to the fact that a module was cached,
it was not possible to close the file_stream anywhere.
file_stream will start emitting PendingDeprecationWarnings in
astroid 1.4, DeprecationWarnings in astroid 1.5 and it will
be finally removed in astroid 1.6.
* Add inference tips for 'tuple', 'list', 'dict' and 'set' builtins.
* Add brain definition for most string and unicode methods
* Changed the API for Class.slots. It returns None when the class
doesn't define any slots. Previously, for both the cases where
the class didn't have slots defined and when it had an empty list
of slots, Class.slots returned an empty list.
* Add a new method to Class nodes, 'mro', for obtaining the
the method resolution order of the class.
* Add brain tips for six.moves. Closes issue #63.
* Improve the detection for functions decorated with decorators
which returns static or class methods.
* .slots() can contain unicode strings on Python 2.
* Add inference tips for nose.tools.
What's New in astroid 1.3.2?
============================
Release date: 2014-11-22
* Fixed a crash with invalid subscript index.
* Implement proper base class semantics for Python 3, where
every class derives from object.
* Allow more fine-grained control over C extension loading
in the manager.
What's New in astroid 1.3.1?
============================
Release date: 2014-11-21
* Fixed a crash issue with the pytest brain module.
What's New in astroid 1.3.0?
============================
Release date: 2014-11-20
* Fix a maximum recursion error occurred during the inference,
where statements with the same name weren't filtered properly.
Closes pylint issue #295.
* Check that EmptyNode has an underlying object in
EmptyNode.has_underlying_object.
* Simplify the understanding of enum members.
* Fix an infinite loop with decorator call chain inference,
where the decorator returns itself. Closes issue #50.
* Various speed improvements. Patch by Alex Munroe.
* Add pytest brain plugin. Patch by Robbie Coomber.
* Support for Python versions < 2.7 has been dropped, and the
source has been made compatible with Python 2 and 3. Running
2to3 on installation for Python 3 is not needed anymore.
* astroid now depends on six.
* modutils._module_file opens __init__.py in binary mode.
Closes issues #51 and #13.
* Only C extensions from trusted sources (the standard library)
are loaded into the examining Python process to build an AST
from the live module.
* Path names on case-insensitive filesystems are now properly
handled. This fixes the stdlib detection code on Windows.
* Metaclass-generating functions like six.with_metaclass
are now supported via some explicit detection code.
* astroid.register_module_extender has been added to generalize
the support for module extenders as used by many brain plugins.
* brain plugins can now register hooks to handle failed imports,
as done by the gobject-introspection plugin.
* The modules have been moved to a separate package directory,
`setup.py develop` now works correctly.
What's New in astroid 1.2.1?
============================
Release date: 2014-08-24
* Fix a crash occurred when inferring decorator call chain.
Closes issue #42.
* Set the parent of vararg and kwarg nodes when inferring them.
Closes issue #43.
* namedtuple inference knows about '_fields' attribute.
* enum members knows about the methods from the enum class.
* Name inference will lookup in the parent function
of the current scope, in case searching in the current scope
fails.
* Inference of the functional form of the enums takes into
consideration the various inputs that enums accepts.
* The inference engine handles binary operations (add, mul etc.)
between instances.
* Fix an infinite loop in the inference, by returning a copy
of instance attributes, when calling 'instance_attr'.
Closes issue #34 (patch by Emile Anclin).
* Don't crash when trying to infer unbound object.__new__ call.
Closes issue #11.
What's New in astroid 1.2.0?
============================
Release date: 2014-07-25
* Function nodes can detect decorator call chain and see if they are
decorated with builtin descriptors (`classmethod` and `staticmethod`).
* infer_call_result called on a subtype of the builtin type will now
return a new `Class` rather than an `Instance`.
* `Class.metaclass()` now handles module-level __metaclass__ declaration
on python 2, and no longer looks at the __metaclass__ class attribute on
python 3.
* Function nodes can detect if they are decorated with subclasses
of builtin descriptors when determining their type
(`classmethod` and `staticmethod`).
* Add `slots` method to `Class` nodes, for retrieving
the list of valid slots it defines.
* Expose function annotation to astroid: `Arguments` node
exposes 'varargannotation', 'kwargannotation' and 'annotations'
attributes, while `Function` node has the 'returns' attribute.
* Backported most of the logilab.common.modutils module there, as
most things there are for pylint/astroid only and we want to be
able to fix them without requiring a new logilab.common release
* Fix names grabbed using wildcard import in "absolute import mode"
(ie with absolute_import activated from the __future__ or with
python 3). Fix pylint issue #58.
* Add support in pylint-brain for understanding enum classes.
What's New in astroid 1.1.1?
============================
Release date: 2014-04-30
* `Class.metaclass()` looks in ancestors when the current class
does not define explicitly a metaclass.
* Do not cache modules if a module with the same qname is already
known, and only return cached modules if both name and filepath
match. Fixes pylint Bitbucket issue #136.
What's New in astroid 1.1.0?
============================
Release date: 2014-04-18
* All class nodes are marked as new style classes for Py3k.

retrieve their metaclass.
* Add a new YieldFrom node.
* Add support for inferring arguments to namedtuple invocations.
* Make sure that objects returned for namedtuple
inference have parents.
* Don't crash when inferring nodes from `with` clauses
with multiple context managers. Closes #18.
* Don't crash when a class has some __call__ method that is not
inferable. Closes #17.
* Unwrap instances found in `.ancestors()`, by using their _proxied
class.

=============================
Release date: 2013-07-29
* Fix some omissions in py2stdlib's version of hashlib and
add a small test for it.
* Properly recognize methods annotated with abc.abstract{property,method}
as abstract.
* Allow transformation functions on any node, providing a
``register_transform`` function on the manager instead of the
``register_transformer`` to make it more flexible wrt node selection
* Use the new transformation API to provide support for namedtuple
(actually in pylint-brain, closes #8766)
* Added the test_utils module for building ASTs and
extracting deeply nested nodes for easier testing.
* Add support for py3k's keyword only arguments (PEP 3102)
* RENAME THE PROJECT to astroid

instance attribute
What's New in astroid 0.14.0?

* This package has been extracted from the logilab-common package, which
will be kept for some time for backward compatibility but will no
longer be maintained (this explains that this package is starting with
the 0.13 version number, since the fork occurs with the version
released in logilab-common 0.12).
